3.
Slave Reader/Writer No. 1 will communicate with the RF Tag using the Once communications option.
Here, communications will end normally or an RF Tag communications error will occur, the Reader/
Writer will return a response to the host device, and processing will end. If an RF Tag tag missing error
is detected, processing will be continued in order by Slave No. 2 and then by Slave No. 3.
4.
If an RF Tag missing error is detected for Slave No. 3, communications processing is returned to the
Master Reader/Writer and the operation is repeated from step 2.
In Field Extension Mode, the Reader/Writers do not simultaneously perform communications. The Reader/Writer
individually perform communications on a time sharing basis.
